摘　　要：为解决弧门水推力大闸墩布筋困难这一难题,尼尔基溢洪道闸墩采用了预应力混凝土结构,锚固体系采用了OVM锚具和高强低松弛钢绞线。本文对预应力闸墩的锚束布置、张拉力设计、锚固体系选择以及空间有限元计算成果作了简要介绍。The prestressed concrete structure is adopted in the spillway pier of Nierji water complex for solving the difficult problem of large push of radial gate and difficult reinforcement in gate pier. The anchorage system-anchorage device OVM-and high strength and low relaxation steel tendon are adopted. The paper introduces the arrangement of anchor sheaf in gate pier, the design of tension, the selection of anchorage system and the result of space finite element calculation.
